Definitions

  • the invention relates to a locking bolt for the sash of windows, doors or the like.
  • it has a turnstile for the sash of tilt and turn windows and doors.
  • He or she consists of a spring catch with a realistically small bolt engagement depth predetermined by the spring travel, and of a slide bolt that can be actuated by a handle and an engagement depth that exceeds the bolt engagement depth of the spring catch.
  • locking latches are known, which have a spring catch with a relatively small latch engagement depth predetermined by the spring travel into the associated latch loop (DE-GM 16 95 429).
  • Locking bolts are already part of the state of the art, which can only be brought into the release position from their bolt engagement position by persons authorized to do so, in a special way operating handle that can be engaged and disengaged is assigned (DE-GM 16 96 711).
  • the operating handle which can be engaged and disengaged, cooperates with a locking bolt designed as a spring catch, ie there is no sliding bolt that can only be manually shifted between its release position and its bolt engagement position.
  • the invention is now aimed at creating a locking bolt of the type described in the introduction, in which only the slide bolt which can be manually displaced between its release position and its bolt engagement position by its attached operating handle can be blocked against disengagement in its engagement position, while the spring catcher does so can bring an operating handle against the restoring force of the spring into its release position, but then returns to its starting position in a spring-locked manner, in which it can automatically cooperate with the locking loop assigned to it.
  • a locking bolt according to the invention which fulfills this task, is fundamentally characterized in that the handle of the slide bolt carries a rotary knob protruding into a slot-shaped or groove-shaped recess of the stationary slide-bolt guide, that the slot-shaped or groove-shaped recess of the stationary slide-bolt guide carries at least on its maximum locking engagement depth of the slide bolt associated end has an extension, and that the rotary toggle can only be rotated transversely into a blocking position within this extension.
  • An advantage of a locking bolt equipped with the aforementioned features is that the spring catch can be relieved of its locking function as long as the slide bolt is blocked in its engagement position against unlocking. On the other hand, however, the spring catch can be fully effective as soon as the slide bolt has been moved back into its basic or initial position by means of the handle.
  • the rotary toggle has a flat web, the width of which is matched to the width of the slot or groove-like recess, while its length corresponds at least approximately to the opening dimension of the extension. In this way, the rotary toggle is secured against displacement from the release into the blocking position, as long as the slide bolt does not assume its bolt engagement position.
  • the rotary toggle sits in a cylindrical chamber open to the rear of the handle, the end wall of which is provided with a profile opening, and that it contains a profile channel facing the profile opening, a socket wrench being provided as the actuating element, which on the one hand leads to the profile channel and on the other hand fits the profile breakthrough. Only people who have a suitable socket wrench are able to release the slide bolt that is blocked in the bolt engagement position, for example, for cleaning the outside of the window sash or for brief burst ventilation of the room.
  • the operation of the locking bolt according to the invention is facilitated if the angle of rotation of the rotary knob within the cylindrical chamber, e.g. is limited to 90 °, with a stop lug on the periphery of the rotary knob engaging in an arcuate groove of the chamber.
  • Another design for a locking bolt according to the invention is characterized in that that the rotary toggle carries an approximately semicircularly delimited pin, the flat semicircular surface of which lies on the axis of rotation of the rotary toggle, that the expansion of the slot or groove-shaped recess in the fixed slide lock guide has a circular shape and is offset on one side at the end assigned to the maximum lock engagement depth of the slide lock connects this recess, and that the angle of rotation of the rotary knob within the cylindrical chamber is limited to 180 ° by a stop lug on its periphery which engages in an arcuate groove of the chamber.
  • the locking bolt for the sash of windows and doors or the like shown in the drawing is used in particular as a turnstile for the sash of tilt and turn windows and doors.
  • turnstiles are required on the one hand if - for example in schools, hospitals, sanatoriums or the like. - It is to be prevented that the window or door leaves can be opened by unauthorized persons in the rotational position. On the other hand, the use of such turnstiles is also recommended or even a requirement if one of the sashes is in the tilt-open position in the case of double-sash windows and then the closed neighboring sash must be blocked against unwanted opening from the outside - in order to prevent break-ins. In each of the two aforementioned applications, it is important that the locking bolt can be installed in a position that does not prevent or impair the opening of the sash.
  • the locking bolt or the turnstile basically comprises two interacting components, namely on the one hand the actual locking device 1 and on the other hand the locking engagement 2.
  • the locking device 1 is, for example, preferably on the wing of the window or door the rollover circumferential surface of the same, fastened, while the locking engagement 2 is then attached to the room-side end face of the frame.
  • the arrangement can also be provided vice versa, so that the bolt engagement 2 with the wing and the bolt device 1 is connected to the frame of the window or door.
  • the simplest component of the locking bolt or the turnstile is the bolt engagement 2, namely it consists of a fastening plate 3 and an engagement grommet 4 that is rigidly attached to it and is open at least at one end.
  • the locking device 1 has a housing 6 carried by screw-on plates 5, in which a locking bolt 7 is guided in a longitudinally sliding manner.
  • the end 8 of the locking bolt 7 emerging from the housing 6 interacts with the grommet 4 of the locking engagement 2 and is provided with a run-up slope 9 on its rear for this purpose.
  • a handle 10 which is slider-like in a recess in the housing 6, which is provided below a screw-on plate 5 and in front of a rear wall 11 of the housing 6 adjoining it at right angles.
  • the locking bolt 7 is coaxially surrounded by a helical compression spring 13, which is supported on the one hand on a transverse wall 14 of the housing 6 and on the other hand engages a collar 15 of the locking bolt 7, which, for example, engages in a circumferential groove of the same used snap ring can be formed.
  • the helical compression spring 13 is designed so that it normally tries to hold the locking bolt 7 in the advanced basic or initial position shown in FIG. 3. Contrary to the restoring force of the helical compression spring 13, however, the locking bolt 7 can be pushed further into the housing 6 if its front end 8 with its rear run-up slope 9 occurs on the opening edge of the grommet 4 of the locking engagement 2 on the frame during a closing movement of the wing. After driving over the opening edge of the grommet 4, the locking bolt 7 then snaps back under the action of the helical compression spring 13 into its basic or starting position, so that in this way the locking device 1 interacts with the locking engagement 2 as a spring catch with a relatively low locking engagement depth.
  • the relatively small latch engagement depth of the spring catch is limited by a spring catch device 16 effective between the housing 6 and the latch bolt 7, which is formed on the one hand by a spring wire bracket 17 supported in the housing 6 and on the other hand by a flat trough 18 on the circumference of the latch bolt 7 .
  • the length of the flat trough 18 is dimensioned so that it allows the unimpeded deflection of the locking bolt 7 against the force of the coil spring 13 in the housing 6.
  • the locking bolt 7 can be advanced, overcoming the locking device 16, beyond the spring catch active position shown in FIG. 3, into the greater locking engagement depth, which can be seen in FIG. 1, relative to the engagement sleeve 4 of the locking engagement 2.
  • the locking bolt 7 together with the grommet 4 of the locking engagement 2 forms a conventional sliding bolt.
  • the handle 10 of the locking bolt 7 carries a rotary toggle 21 which is provided on its rear side with a projecting flat web 22 .
  • This flat web 22 projects into a slot or groove-shaped recess 23 which is provided in the rear wall 11 of the housing 6.
  • the flat web 22 of the rotary toggle 21 has a width which is matched to the width of the slot-like or groove-like recess 23, but has a length which exceeds the width of the slot-like or groove-like recess 23, the rotary toggle 21 cannot be actuated , as long as it is in the area of the slot-like or groove-like recess 23.
  • the length of the slot-like or groove-like recess 23 in the rear wall 11 of the housing 6 is now such that the flat web 22 of the rotary knob 21 only completely disengages from it when the locking bolt 7 is moved with the aid of the handle 10 into that of FIG. 1 removable slide lock functional position has been brought.
  • the slot-shaped or groove-shaped recess 23 is followed by an extension 24 incorporated into the rear wall 11, the dimension of which exceeds the length dimension of the flat web 22 located on the rotary toggle 21.
  • the rotary toggle 21 can therefore be adjusted so that its flat web 22 reaches the position shown in FIG. 2 from the position shown in FIG. 4 determined by the course of the slot-shaped or groove-shaped recess 23 by 90 °.
  • the locking bolt 7 is then securely blocked in its push-lock functional position according to FIG. 1 against retraction from the grommet 4 of the locking engagement 2 with the aid of the handle 10.
  • the rotary toggle 21 sits in a cylindrical chamber 25 (FIG. 2) which is open towards the rear of the handle 10 and whose end wall is provided with a profile opening 26 (FIGS. 1 and 3).
  • This profile opening 26 can have a cross-shaped or + -shaped outline shape, as indicated in FIGS. 1 and 3.
  • the rotary knob 21, on the other hand, is equipped in its end facing the profile opening 26 with a profile channel 27 which, for example, has a flat, rectangular outline shape and is provided with gradations in the direction of its depth or in the direction of the longitudinal axis of the rotary knob 21.
  • a suitable key-like actuating tool can be inserted through the profile opening 26 in the handle 10 into the profile channel 27 of the rotary knob 21, with the help of which the rotary knob 21 can be shifted by 90 ° between the two functional positions according to FIGS. 2 and 4.
  • a stop lug 28 on the circumference of the rotary knob 21 can engage in an arc groove 29 on the circumference of the chamber 25, as is shown in the drawing.
  • the locking bolt 7 fulfills a double function, namely a spring catch function in the position shown in FIG. 3, and a slide bolt function in the position shown in FIG. 1.
  • a catch latch can preferably be slidably guided in the housing 6 of the locking device 1 and acted upon by a spring element corresponding to the helical compression spring 13 such that it is normally held in a position corresponding to FIG. 3, from which it counteracts the spring force into the housing 6 can spring back.
  • a locking bolt similar to locking bolt 7 is displaceably guided as an independent functional element with the aid of handle 10.
  • the slide bolt In the operating position of the handle corresponding to FIG. 3, the slide bolt is retracted so far into the housing 6 that its front end is at least flush with the front wall of the housing from which the spring catch projects.
  • FIG. 1 Another deviation from the exemplary embodiment of a locking bolt or a rotary lock explained with reference to the drawing may also consist in the fact that an either rotatable or axially displaceable locking cylinder is installed in the handle 10 instead of the rotary knob 21 as a blocking element.
  • an either rotatable or axially displaceable locking cylinder is installed in the handle 10 instead of the rotary knob 21 as a blocking element.
  • this can carry the flat web 22 on the back, so that the rest of the effect of the blocking device corresponds to the embodiment shown.
  • a pressure cylinder it is expedient to assign an engaging hole to a locking pin located on the rear side thereof in the rear wall 11 of the housing 6 only where the slide bar pushed out in the operative position is to be fixed.
  • the extension 24a of the slot-shaped or groove-shaped recess 23 in the rear wall 11 of the housing 6 has a circular shape at the end assigned to the maximum bolt engagement depth of the bolt 7. It adjoins the slot-shaped or groove-shaped recess 23, offset on one side, as can be clearly seen in FIGS. 5 and 6.
  • the angle of rotation for the rotary toggle is limited within the cylindrical chamber 25 of the handle 10 by a stop lug 28a on its circumference to 180 °.
  • the stop lug 28a engages in an arc groove 29a of the chamber 25.
  • the profile opening 26 in the end wall of the handle 10 does not have to have a cross-shaped or + -shaped outline shape, but rather flat-rectangular - to match the profile channel 27 in the rotary knob 21 - can be performed.
